#2: All sounds must be done and only be done using any parts of your body. No other objects allowed.

#3: Not less than one sample must be recorded as a "loop" with a length of at least one bar. This could be a human beatbox rhythm, a whistled melody, spoken words, singing, a rhythm made with your hands on your leg, etc.

#4: The loop from rule #3 must appear at least once in its full length and as it was originally recorded (applying effects is allowed). Apart from that it can be chopped up and scattered as much as you want.

#5: Unlimited resampling and all effects allowed.

#6: The title of your submission must contain at least the name of one body part that you used fulfilling rule #2. Some examples: "Hand me your heart", "Kneedeep in trouble ", "I head an awful trip". (Let's not drift into NSFW regions here.)

...and finally the golden OP-1 battle rule...

#7: all mixing, processing, recording, mastering and final mixdown to album must take place within the OP-1 (you may use an external microphone and recording device for recording your body sounds, but no external effects or processing allowed!).

I just wanted to say, that the battles idea is great. Even if you don’t win or whatever, just through taking part you will discover new approaches to making music and also probably finish some tracks. With the plans laid out already, you have enough criteria to get a track going.

#7: .....(you may use an external microphone and recording device for recording your body sounds, but no external effects or processing allowed!).

Was struggling to get the samples I wanted out of the OP1 mic and a plugged into the OP1 wasn’t working for me… so I came back to check this rule before proceeding! Whew!!! Carry on! Sternum-Bass drum, engage!
